Fault Display and Corrective Actions at Auto-tuning
The following are fault displays and corrective actions at auto-tuning. If any of the following faults
are found, the digital operator displays that fault contents; the motor coasts to stop if it is under
operation. Fault contact output or minor fault contact output does not operate.
Fault Display Fault or Indicator Name/Description Corrective Action
Er-01
Fault
Motor Data Fault . Motor data input fault for
auto-tuning. Relationship between motor output
and motor rated current fault. Relationship
between input motor rated current and set no-load
current fault (at vecotr control mode and line-to-
line resistance tuning.)
• Check input data.
• Check inverter and motor capacity
• Check motor rated current and no-load current.
Er-02
Minor Fault
Alarm . The minor fault is detected during auto-
tuning.
• Check input data.
• Check wirings
• Check load.
Er-03
STOP Key
STOP Key Input . The stop key is pressed during
auto-tuning.
•
Er-04
Resistance
Line to Line Resistance Fault . Auto-tuning is not
completed within the expected time. The auto-
tuning is outside the parameter setting.
• Check input data.
• Check motor wiring.
• If a motor and a load are connected, disconnect
the motor from machinery system.
Er-05
No-Load Current
No-load Current Fault. Auto-tuning is not
completed within the expected time. The auto-
tuning is outside the parameter setting.
Er-08
Rated Slip
Rated Slip Faul t. Auto-tuning is not completed
within the expected time. The auto-tuning is
outside the parameter setting.
Er-09
Accelerate
Acceleration Fault . The motor did not accelerate
at the expected time.
• Increase B5-01 (acceleration time).
• If C7-01 and C7-02 (torque limit value) are
decreased, increase values.
• If a motor and a load are connected, seperate the
motor from the load.
Er-11
Motor Speed
Motor Speed Fault (Rotation type tuning only).
The motor speed was over 100% at auto-tuning
(vector control without PG only).
• Increase B5-01 (acceleration time).
• If a motor and a load are connected, seperate the
motor from the load.
Er-12
I.det.Circuit
Current Detection Fault. Current exceeded the
motor rated current.
• Release brake.
• Check for open motor lead.
Er-13
Leakage Inductance
Leakage Inductance Fault . Auto-tuning did not
finish within the set time.
• Check the T1 parameters.
• Check motor wiring.
End 1
V/F Oversetting
Excess V/f setting * (Rotation type tuning only).
The torque reference exceeded 100% and no load
current exceeded 70%.
• Check the T1 parameters.
• Disconnect the motor from the load.
End 2
Saturation
Motor Iron Core Saturation Coefficient Fault
(Rotation type tuning only)
Since the motor iron
core saturation coefficient could not be auto-tuned
within the set time, tentative value is set in the iron
core saturation coefficient
.
• Check the T1 parameters.
• Check motor wiring.
• Disconnect the motor from the load
End 3
Rated FLA Alm
Rated Current Set Alarm . Motor current during
tuning was greater than the set value.
• Check E2-01.
NOTE: * Excessive V/f set value, motor iron core saturation coefficent fault, and rated current set alarm are displayed after
the auto tuning is completed.
